Cassini Resources Limited: Assays Confirm Potential of H-T Lode at Babel
(firmenpresse) - Assays Confirm Potential of H-T Lode at Babel
HIGHLIGHTS-
- Extension drilling at the Babel Deposit intersects broad zone of nickel and copper mineralisation - 25.6m (at) 0.63% Ni, 1.04% Cu
- Probable offset of the Startmeup Shoot
- DHEM indicates mineralisation may extend over 300m
- Follow-up drilling planned to test strike extensions
- Potential positive implications for Babel development scenarios
Cassini Resources Limited (ASX:CZI) (Cassini or the Company) is pleased to announce early success from extension drilling at the Babel Deposit, part of the West Musgrave Project (WMP or the Project) in Western Australia. The program is funded as part of the Earn-in/JV Agreement (JV or the Agreement) with OZ Minerals Limited (ASX:OZL) (OZ Minerals). The JV Partners are currently undertaking a Pre-feasibility Study (PFS) on the Nebo-Babel Deposits with a concurrent regional exploration program. This announcement follows the reporting of visual observations from drilling on 21 June 2018.
The H-T Lode
Diamond drillhole CZD0077 is the first hole to test a strong Moving Loop Electromagnetic (MLEM) and coincident Down Hole Electromagnetic (DHEM) conductor representing an extension to the Babel Deposit. The hole has intersected 25.6m (at) 0.63% Ni, 1.04% Cu, 0.03% Co, 0.23g/t PGE and 0.11g/t Au from 317.3m, hosted with a 34m zone of gabbronorite.
This hole is consistent with the nearest drill hole, WMN4049, with an intercept of 25.1m (at) 0.94% Ni & 0.94% Cu, 0.03% Co, 0.28g/t PGE and 0.11g/t Au from 311.6m. This intercept lies approximately 50m east of CZD0077 (Figure 1).
This mineralised zone known as the H-T Lode appears to be the faulted extension of the Startmeup Shoot and demonstrates a similar style of mineralisation, grade and geometry (Figure 1). The H-T Lode now represents a significant target as an extension to the proposed Babel open pit design either by cut-back or through underground mining.

Figure 1. H-T Lode Plan showing location and intercepts of CZD0077 and WMN4049.
The JV Partners are encouraged with this early success to the resource extension program which demonstrates the potential up-side to the existing Nebo-Babel resource.
The diamond rig is currently drilling other extension and infill targets at Nebo and Babel. A follow-up hole will be drilled to test mineralisation along strike to the west, which is currently open, following completion of DHEM and geological interpretation. A second diamond rig has recently started drilling at the One Tree Hill Prospect following the Companys systematic plan for regional exploration throughout 2018 (Figure 2).

About the Company
Cassini Resources Limited (ASX: CZI) is a base and precious metals developer and explorer based in Perth. In April 2014, Cassini acquired its flagship West Musgrave Project (WMP), located in Western Australia. The Project is a world-class asset which currently has over 1.0 million tonnes of contained nickel and 2.0 million tonnes of contained copper in Resource. The Project is a new mining camp with three existing nickel and copper sulphide deposits and a number of other significant regional exploration targets already identified. The WMP is the largest undeveloped nickel - copper project in Australia.
In August 2016, Cassini entered into a three-stage $36M Farm-in/Joint Venture Agreement with prominent Australian mining company OZ Minerals Ltd (ASX: OZL). The Joint Venture provides a clear pathway to a decision to mine and potential cash flow for Cassini.
Cassini is also progressing its Mt Squires Gold Project, an early stage zinc exploration project in the West Arunta region and also has an option to acquire 80% of the Yarawindah Nickel - Copper - Cobalt Project, all located in Western Australia.
Competent Persons Statement
The information in this report that relates to Exploration Results is based on information compiled or reviewed by
Mr Greg Miles, who is an employee of the company. Mr Miles is a Member of the Australian Institute of Geoscientists and has sufficient experience of relevance to the styles of mineralisation and the types of deposits under consideration, and to the activities undertaken, to qualify as a Competent Person as defined in the 2012 Edition of the Joint Ore Reserves Committee (JORC) Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. Mr Miles consents to the inclusion in this report of the matters based on information in the form and context in which it appears.
The Company is not aware of any new information or data, other than that disclosed in this report, that materially affects the information included in this report and that all material assumptions and parameters underpinning Exploration Results, Mineral Resource Estimates and Production Targets as reported in the market announcements dated 3 April 2014, 1 May 2017, 14 November 2017 continue to apply and have not materially changed.
